The long-haired, shaggy coat is grizzled dark brown or black to reddish brown. The fur on the legs is short and sleek. Water mongooses are good swimmers, often submerging themselves, with only the nose exposed. The palms of the feet are naked.A rare mongoose species in Kruger, most reports being from Sabie River, but there have also been reports from the Olifants, Levhuvhu, and Madzaringwe rivers. They like habitats with water.

The contact calls include grunts, snorts, meows, bleats and purrs. Alarm calls include screams, barks and growls.Alarm signals: Bristle hair on the back and neck to appear larger. Often flee to water when threatened, fully submerging themselves leaving only the nose exposed.Aggression is shown as they bristle their hair on the back of the neck to appear larger. Staring, crouching, with open-mouthed gape, rushing snapping and biting. To deter predators, an odourous liquid is discharged from the anal glands while backing away of rolling into a ball.

Predominantly nocturnal, and can be active at dawn and dusk. Predominantly solitary. Home-ranges are marked with cheek gland secretions, with black and gland secretions that turn creamish with age, and with urine and dung middens. Home-ranges include well-defined paths that run along shore lines. Abandoned burrows, termite mounds and thick vegetation is used as burrows.

Breed in the summer rainy season. 1-3 cubs, weighing 125g each, are born after a gestation period that is presumed to be 60 days. Cubs are born in a nest made of grass, reeds and sticks, in burrows, termite mounds and hollow trees and logs. They are blind at birth and fully furred. Their eyes and ears open at 3 weeks, and they are weaned at 1 month.

Great Photos I've seen these guys in the Shingwetsi Camp before, aswel as below the Skukuza restuarant........Also in Roodeplaat Dam NR, and found the spoor on my property in the Waterberg! Always solitary, and to skittish for a photo!!

Because us birding oaks do what we do (sit quietly hours on end...) we sometimes get some very special mammal sightings... Like this critter that came so close to my car that I battled to it in get focus!

Innitially I had no idea what this was. Only later on when I hit the books did I realise what a special sighting this was!

I got some lekka info from the Googling: This is a large and robust mongoose. It reportedly can weigh up to 4kg. This animal has a large brain that is associated with increased tactile sensitivity and muscular control of the forepaws. These characteristics enable the semi-aquatic mongoose to locate and eat crabs and other relatively hard-bodied prey. Their teeth are adapted to crush the hard outer shells of shell fish, rather than to shear. This is the only member of the family Herpestidae with unwebbed feet that splay on soft substrates. This trait results in a very distinctive spoor.

They are supposedly solitary in habits, a semi-aquatic and nocturnal species. Supposedly so I say, because I saw six of them running together down well-defined pathways along the shorelines of the road underneath the power lines that cross the wetlands near the Hadeda Bird Hide in the Marievale bird sactuary.

An interesting habit they use to catch a bird: the mongoose lies on its back and looks as if it's sunbathing. In this position, the pale, pink anal area assumes a startling prominence against the surrounding dark fur. This display is claimed to induce birds to approach and peck at the anus, whereupon the mongoose seizes the bird.

When the mongoose is cornered or distressed, it reportedly ejects jets of foul brown fluid from its anal sacs.
